We had a similar problem, arcing throughout cooking cycle but microwave heats properly, and it doesn't happen consistently. The waveguide was missing, we can't be sure it was always there because we're not the original owners, but we installed one and the arcing is better but not gone altogether. No burn marks anywhere inside the oven, and the inside of the oven is clean. If it matters, it's a GE SCA2001 We had a similar problem, arcing throughout cooking cycle but microwave heats properly, and it doesn't happen consistently.

{ MAGNETRON FAILURE }
I cut the magnetron right down the center. I can see why so many GE magnetron fail. They have a poor Filament design. The sparial spring that completes the filmanet circuit on the cathode will become brittle over time and will surely fail. I am a layman when it comes to this design. I see no GE
magnetron with this filament design lasting 10 years.

There are some times when it is ok to use metallic stuff in a
microwave. This is probably one of them. But you won't get
the manufacturer to agree. Metal concentrates the microwave
energy making a strong enough local electric field to cause sparks and
heat. Usually burns that spot. Do you have one of those
popcorn cookers for microwaves? Works by heating a special pad in
the bottom just right.
What the manufacturer is saying in the warning is:
Don't sue us if you use metal in this oven and something goes wrong.
